Hose-Free Liquid Spray Container With Integrated Outflow Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid containers with pumps for dispensing content, such as cosmetic containers, often have an aesthetic issue due to the visible hose that connects the pump to the container body, which can be mitigated by omitting the hose and using an improved channel structure.
Innovation Solution
A container design with a partitioned body and cover that includes a body outflow channel, pump support, and body cover, allowing for the pump to be integrated without a visible hose, maintaining pressure through external air inflow channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hose is inserted into the container body to enable the pump to suction content, then the pump can completely dispense the content, but the hose becomes visible from the outside and lowers the aesthetic appearance
Solution Approach 1:
The hose is completely removed from the system. Instead of inserting a hose into the container body, the invention integrates the content discharge function directly into the container wall through a hole formed in the partition wall, eliminating the aesthetic problem while maintaining dispensing functionality
Solution Approach 2:
The container body and pump are merged into a single integrated structure where the partition wall of the container body directly forms the discharge channel. The hole in the partition wall serves as both the discharge opening and the pump inlet, combining multiple functions into one structure
2Shape
If the container body is made opaque to hide the hose, then the aesthetic issue is mitigated, but the overall design complexity increases and transparency is lost
Solution Approach 1:
By removing the hose entirely, the invention eliminates the need to choose between opaque and transparent materials for aesthetic reasons. The transparent container body can now be used without compromise, as there is no visible hose to hide
Solution Approach 2:
Instead of hiding the hose by making the container opaque, the invention inverts the approach by making the hose invisible through complete removal and direct integration of the discharge function into the container structure
3Productivity
If a hose is used to connect the pump to the container bottom, then content can be suctioned effectively, but the structure becomes more complex with additional components
Solution Approach 1:
The container partition wall and the discharge channel are merged into a single structure. The hole in the partition wall directly serves as the pump inlet, eliminating the need for a separate hose and reducing structural complexity while maintaining suction efficiency
Solution Approach 2:
The hose is extracted from the system and its function is transferred to the container wall structure itself, simplifying the overall design while maintaining the same content delivery performance

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a simplified structure with improved aesthetics by eliminating the need for a visible hose and maintaining effective dispensing functionality.
Implementation Method 1
configured to support the pump and prevent outside air from entering the pump insertion space

AI summary
A container for spraying liquid includes a body, a body cover, a pump, a pump support, and a shoulder. The body has an inside divided into a filling space and a body outflow channel by a partition having an upper body hole and a lower body hole. The body cover is coupled to an upper portion of the body and includes a cover channel communicating with the upper body hole and a pump insertion space communicating with the cover channel. The pump support is coupled to an upper portion of the body cover to support the pump. The shoulder is coupled to an upper portion of the pump support to press down the pump.
